Why does Electrum embody seemingly pointless inputs in a transaction?


I wish to make a fee of x BTC.

My Electrum pockets reveals two “output factors” within the Cash tab (with the identical handle). Each of those present an quantity a lot bigger than x BTC.

If go to the Ship tab and begin to make a fee to an handle, then click on “Pay…” after which “Superior”, I can see two inputs, which appear to correspond to the 2 “output factors” within the Cash tab and present the identical quantities. The transaction measurement is 447 bytes. I abandon this transaction.

If I am going to the Cash tab, proper click on on one of many two “output factors” and select “Spend”, Electrum reveals a inexperienced banner saying “Coin management energetic”. If I begin to make the identical fee, the “Superior” dialog now solely reveals one enter and the transaction measurement is 226 bytes.

This seems to me as if I could make the identical transaction and incur a smaller payment through the use of “coin management”. Am I lacking one thing? Is there an obstacle or threat to doing this? I am pondering there should be, in any other case Electrum would simply do it mechanically.

I may perceive needing two inputs to the transaction if x was greater than the quantity related to every one among my two “output factors”, but it surely is not.
